The bathroom is your personal sanctuary, the place where you have lots of time to wonder. Like, why’s it called the John? Why not the Charlie? Are the blow hand dryers really better than paper? Why does the door in public restrooms always open inward?

Have you ever thought of why some public bathrooms tell you not to flush the toilet paper? Or why public toilet seats are shaped like a U? Or if the plumbing is underground, how can wind affect the water in your commode? So many questions. Let’s try to answer them!

  • When you use a hand dryer, it can blow bacteria around you – even though the air coming from it is perfectly clean!
  • Even though toilet paper is supposed to break down when it gets wet, there’s still a possibility of clogging if the plumbing system isn’t new or if you use too much of it.
  • The “open-flush” toilets in public restrooms don’t have a lid to block all the germy microscopic droplets that come spewing out with each flush.
  • The gap on the front of the seat that makes it look like a horseshoe is there because of plumbing codes. Since 1995, all public toilets must have this open seat.
  • Bacteria and viruses are tiny enough to easily soak in through the paper the covers are made of.
  • You can find toilet paper in different colors on the market. But most manufacturers bleach it to make it softer.
  • No one knows for sure, but some think that this name appeared back in the 16th century when Sir John Harrington invented Britain’s first flushing toilet.
  • In many homes, there’s a vent pipe that goes outside to the roof. When the wind blows hard above that pipe, the air pressure in it is lowered.
  • Most American toilets use a syphonic system, which forcibly draws toilet water down the drain.
